9d0d16cffd nvgpu: add insturmentation for ctxsw error codes 
For integration testing in safety build, we need to test ctxsw firmware
error codes. inorder to test this, we need some instrumentation in
nvgpu driver.

Added below instrumentation for CTXSW FW error code integration testing.

 1. Reduce the ctxsw watchdog time, so ctxsw watchdog always triggered.
    Use CONFIG_NVGPU_CTXSW_FW_ERROR_WDT_TESTING for testing watchdog

 2. Submit unsupported method to CTXSW FW, it will trigger err.
    Use CONFIG_NVGPU_CTXSW_FW_ERROR_CODE_TESTING for testing err code.

bbb63c0a8c gpu: nvgpu: remove "trace/events/gk20a.h" from QNX build 
- "include/trace/events/gk20a.h" file was having GPL2 license
(which should not used for QNX code). This file was used for
compiling linux userspace driver("libnvgpu-drv.so") and was used for
unit testing on QNX.
- This patch removes stubs in "include/trace/events/gk20a.h" file.
(which were used for linux userspace driver.)
- For QNX driver, "nvgpu_rmos/trace/events/gk20a.h" was used.
This patch moves that file to "include/nvgpu/posix/trace_gk20a.h" and
does relevant license change. This same file will be used for linux
userspace driver.
- This patch also creates a new file "include/nvgpu/trace.h" which
selects proper trace file depending on the config.

21f8b366cd gpu: nvgpu: fix misra 2.5 violations 
MISRA Advisory Rule 2.5 states that a project should not contain unused
macro declarations.

While most of the violations in the nvgpu driver are due to unused
macros from hw headers, devinit-related headers, etc. there is a small
number that are due to things like:

 * macros not being used when they could/should be
 * macros in C files that are really not referenced
 * CPP build flag mismatches

This change eliminates such violations from the following:

 * replace constants with existing macros in timeout conversion code
 * wrap nvgpu_gmmu_dbg macro #defines in #ifdef CONFIG_NVGPU_TRACE/#endif
 * wrap MAX_MC_INTR_REGS #define in #ifdef CONFIG_NVGPU_NON_FUSA/#endif
 * remove unused FECS_MAILBOX_0_ACK_RESTORE from runlist code
 * wrap BACKTRACE_MAXSIZE macro with #ifndef _QNX_SOURCE/#endif

In order to get coverage numbers corresponding to the release build
let us remove the overriding of the build profile for safety qnx
build. This also needs that these components are built only for
safety qnx and l4t builds.

For x86 and L4T userspace build, default profile is still set to
